WINDOW SCREEN AND SASH LOCKEB..

Specification of Letters Patent.

Patented Aue. 29V, 1916.

Application filed September 7, 1915. Serial No. 49,299.

To @ZZ whom t may concern:

Be it vknown that T, CLAUDE ELLIS, of Springville, Erie county, New York, United States of America, have invented a Vindow Screen and Sash Locker.

This invention relates to a new and useful device for the purpose of locking the lower window sash of an ordinary window firmly to the ordinary window screen of commerce, and also at the same time locking the upper window sash firmly to its casing. This device is also for the purpose of locking an upper window sash firmly on to the ordinary screen of commerce when put in the upper window space and at the same time lirmly locking the lower sash to its casing. WV hen used in either window space the device prevents the raising and lowering of both windows while the screen is in place, and also serves to lock the window Screen to the window casing. The device is portable anl can be readily and very quickly applied to a window or detached therefrom without scarring or injuring the woodwork in any way.

Figure 1 is a sectional perspective view of a window provided with a sash and screen lock constructed in accordance with this invention, the screen being placed beneath the partially raised lower sash and both sashes and the screen locked in position. Fig. 2 is a view of the device in section for the most part.

3 represents a window ot' ordinary construction, having sliding1 upper and lower sashes t and 5 provided with window panes G. As shown in Fig. 1, the lower sash 5 is raised to admit a wire screen, which is placed in position beneath the lower sash with its ends extending into the sash guideways in the casing. These parts may be of any ordinary and well known construction.

Referring to Fig. 1, 7 represents the window screen and sash locking device. The device consists of a rack and two closely litting casings 9 and 10. Each casing is of metal and is vertically hollow. The cavity in casing 9 is the same shape as the rack represented herein at 8 and is so constructed that the said rack may easily slide vertically up and down inside the same. Referring to Fig. 2. Said casing 9 contains a lateral opening, the vertical length of which is slightly greater than the length of the worm p 14. The lateral opening extends far enough linto the vbody of the casing so that when the rack is assembled in the casing its teeth protrude through the lateral opening. Two jaws 12 and 13 extend into space at right angles to the edge of the casing where the lateral opening occurs at the top and bottom of the lateral opening, Jaw 12 has a threaded recess 17 and jaw 13 has a smooth bored aperture 16. The worm 14: is so threaded that its threads will engage the teeth or the rack 8. This worm is constructed to fit in between the jaws 12 and 13 and possesses a cylindrical cavity along its perpendicular axis of sulhcient bore to admit of the bolt 15. This bo-lt is threaded on its end for a distance equal the depth of the threaded recess 17 in jaw 12 with threads suitable to engage the threads of the thread: ed recess 17, and possesses a head with a groove so that it may be tightened with a screwdriver, and is long enough to pass through the smooth bored aperture 16, the i worm 14C and extend into the threaded recess 17. The perpendicular axis of threaded recess 17 is the same as the perpendicular axis of the smooth bored aperture 16. The smooth bored aperture 1G is fitted to receive the head and shank of the bolt 15. The lateral opening` between the two jaws 12 and 13 and the threaded cavity 17 in jaw 12 and the smooth bored aperture 1G in jaw 13 are all so spaced that when the worm 111 is assembled in the casing by means oi the bolt 15, together with the rack 3, the threads of the said worm will engage the teeth oit the said rack and the casing may be moved up and down the rack by turning the worm. The rack 8, at its top, assumes preferably a cylindrical form with a hole in the center of the top for a screw, but may assume any other form convenient nl'or engaging a casing of a window and for holding a piece of rubber.

11 represents a rubber disk with a screw hole in its center. The disk is of a diameter to nicely fit the circular top of the rack when the rack assumes a cylindrical form at its top. Ti' the top4 of the rack be other than circular, the rubber may be of a iorm to fit same.

18 represents a threaded arm extending laterally from casing 9 and extending at right angles to the rack when assembled in the casing.

19 represents a threaded sleeve, so threaded that its threads will engage the threads .of the arm n13, constituting a means whereby Ill@ the threaded sleeve may be moved outward, the threaded sleeve and the arm together constituting a device adjustable in length to adapt to varying widths of window casings, for the purpose of engaging the under side of the top rail of the upper sash. The arm 18 may not be threaded and may be square or cylindrical in form, in which case the threaded sleeve'19 may be dispensed with; in which event, however, the instrument will not have the range of adaptability possessed by one constructed with a threaded arm together with a threaded sleeve.

Casing l() is of metal and is vertically hollow, the cavity of which is the same shape as the rack represented herein at 8, except the cavity assumes preferably a cylindrical form atY its base as in drawings, although it may assume any other form suitable for admitting a wooden base. If cylindrical in form, it may contain on its inside surface threads for receiving a wooden base threaded to engage the threads of the casing l0, although that construction is not employed in the drawings.

25 represents a wooden base adapted to it into the cavity of casing 10. The wooden base, however, as stated before, may be fastened to casing 10 by a pin, adhesion, threads or any other suitable means. The wooden base may also possess a rubber disk fastened at its bottom by suitable means, although none is employed in the drawings.

Casing 10 is so constructed that the rack will easily slide vertically up and down inside the same. This casing contains a lateral opening identically like the lateral opening in casing 9, the vertical length of which lateral opening is slightly greater than the length of the worm 24, which worm is identically the same in construction as the worm 14.

A jaw 20, identically like jaw 12, extends into space at the top of the lateral opening in casing 10, at right angles to the edge of the casing where the lateral opening occurs and another aw 2l, identically like jaw 13, extends into' space at the bottom of the lateral opening in casing 10, at right angles to the edge of the casing where the lateral opening occurs, the lateral opening extending far enough into the body ,of the easing so that when the rack is assembled in the casing its teeth will protrude through the lateral opening, identically` as in casing 9.

Jaw -20 possesses a threaded recess 26, identically like 17 in casing 9, and in the Y same relative position, and jaw 21 possesses a smooth bored aperture 22, identically like smooth bored aperture 16 in casing 9 and in the same relative position.

Casing 10 is equipped with a bolt 23, identically like bolt 15 in casing 9, and a worm 24, identically like worm 14 in casing 9, al1 so arranged and constructed that when the worm is assembled in the casing by means of bolt 23 and the rack 'is assembled in the casing, that the threads of the worm 24 will engage the teeth of the rack 8 so that the casing may be moved up and down the rack by turning the worm, identically as casing 9 may be moved up and down the rack by turning the worm 14.

Operation: Raise the lower window sash; place in the screen; lower the window on to the screen. Press the rubber top of the device, as assembled, firmly against the ytop of the window casing. Turn the worm in the lower casing until the wooden base of the lower casing is tightly pressed against the top of the lower window sash. Next, adjust the threaded sleeve on the threaded arm of the upper casing until it almost touches the window glass. Then, by means of the worm in the upper casing, run the up per casing up the rack until the said threaded sleeve nicely engages the under side of the top rail oi.' the sash.

When the screen is used in an upper window space instead of a lower window space, adjust the end of the extension sleeve in the upper casing so that it will nicely catch the under side of the top rail of the upper window sash, and turn the worm in the lower casing until the base of the device presses firmly against the top of the lower window sash.
